Hello ALL! I have a problem to plot factor (lets say gender) as a line, or at least both line and point, from ols model: ols1 <- ols(Y ~ gender, data=dat, x=T, y=T) plot(ols1, gender=NA, xlab="gender", ylab="Y", ylim=c(5,30), conf.int=FALSE) If I convert gender into discrete numeric predictor, and use forceLines=TRUE, plot is not nice and true, since it shows values

Hello! I am truing to compile an R-package having c-code. I put foo.c in src/ folder and useDynLib("foo") in NAMESPACE file. When trying R CMD check, I got an error message that shared object 'foo' is not found. Then I did R CMD SHLIB foo.c first. However, after that, I got warnings from R CMD check that there is an object file in /src folder. Even worse is if I run R CMD

Hello, Recently, I have asked for a help with building graphs, and I got few great advices. Now, my appetite is growing :) and I wander how to add legend for two (or more) lines in following example: matplot(DAT[, c(3,4)], type="b", ylim=c(0,8), xaxt="n", yaxt="n", + pch=c(21,22), col="black", lty=c("dashed","solid"), xlab="",

Hello ALL! I am running Fedora 16 x86_64. Due to some dubious problems, that i couldn't resolve, with the TeXLive (2007, which is a default), I removed it. That removed R as well, and some other dependent packages. Then, I installed TeXLive 2011 from CTAN. However, when I wanted to install R, from Fedora's repositories, it asks for some TeX dependencies (for example, tex-preview,

Hello ALL! First, I apologize for sending question that spill-out from the scope of this list. However, you might be essentially the best informants. In brief, I am thinking to give second shot to the Debian. Currently I am using Ubuntu 9.04, but Debian still teases me, so to say. I used to use Debian testing (Lenny at that time), but when Lenny became stable, things became very shaky in

Hello ALL! Some times ago I started to learn and play with Bayesian stuffs. Many advice use of WinBUGS for Bayesian inference Using Gibbs Sampler. However, WinBUGS is discontinued, and now, development is under OpenBUGS. I wasn't lazy, so I installed both and tried out. In more than 90% of cases they give comparable outcome. But in few cases I got substantial differences. Recently, I read nice

Hello! I recently switched to Debian testing OS and explanation at the: http://cran.at.r-project.org/bin/linux/debian/ is a little bit fuzzy. Can anyone give step-by-step how-to have updated R on Debian testing and/or unstable. Thanks in advance! PM

I have installed lme4 library, but when I try something with lmer() function, I receive error message. On the other hand, I can use lme() function from the same library. Are those two the very same function or not? I am a bit confused. I am using: $platform: "i386-pc-linux-gnu" $arch: "i386" $os: "linux-gnu" $system: "i386, linux-gnu" $major: "2"

Hello! I am trying with this question again: I would like to test few distributional assumptions for some behavioral response data. There are few theories about true distribution of those data, like: normal, lognormal, gamma, ex-Gaussian (exponential-Gaussian), Wald (inverse Gaussian) etc. The best way would be via qq-plot, to show to students differences. First two are trivial: qqnorm(dat$X)

Hello! Interesting thing is that I cannot install rgl. It reports: checking for X... no configure: error: X11 not found but required, configure aborted. ERROR: configuration failed for package ?rgl? * Removing ?/usr/local/lib/R/site-library/rgl? I am pretty sure that my X11 is fine. Does anyone know why I got this error message? Best, PM

Hello ALL! Can anyone tell me how to specify qqmath() function with distribution qgamma? In help it is bit vague how to pass shape and scale parameters for gamma. Thank you in advance. Best, PM

Hello ! I am really happy to find this list. I am not new to R but to Debian or Linux in general. Up to now I used R on MS Windows but now I want to use R on Debian lenny. I have absolutely no experience with Debian. I was able to install R 2.11 on my system using the instruction in the readme on CRAN. I can open R in the shell. On windows I used R with the R GUI or with Tinn-R. Is there the

Hello! Can anyone help me to build a graph with the alphanumeric values on x-axis, with two lines (preferably doted and solid, or similar) that present values on y-axes. In a toy example, data frame could be like this: x.orig x.num y1 y2 a 1 0.2 0.4 b 2 0.1 0.1 c 3 0.3 0.3 d 4 0.3 0.15 e 5 0.1 0.05 I can make graph only if I use values converted to numeric in "x.num", but not original

Hello! Can anyone explain me what solve() function does: Gaussian elimination or iterative, numeric solve? In addition, I would need both the Gaussian elimination and iterative solution for the course. Are the two built in R? Thanks! PM

Hello! I am trying to install gtkDevice package, but without success. It is complaining about: * Installing *source* package 'gtkDevice' ... checking for gtk-config... no checking for gtk12-config... no ERROR: Cannot find gtk-config. I am using Ubuntu 6.06, and I cannot find that package in the repositories. Is there a remedy of any kind? What can I do? Best, Petar M.

Hello, I ran two lme analyses and got expected results. However, I saw something suspicious regarding p-level for fixed effect. Models are the same, only experimental designs differ and, of course, subjects. I am aware that I could done nesting Subjects within Experiments, but it is expected to have much slower RT (reaction time) in the second experiment, since the task is more complex, so it

I am using R 2.1.1 on i486-pc-gnu-linux (Ubuntu Breezy). Recently, I bought new laptop HP nx8220 and installed Breezy with a few problems starting X-Windows. Nevertheless, I followed some instruction, managed to start X, and added R from the Ubuntu's repositories. When I try to produce any graph (like plot, bwplot etc.), I receive an error message: can't find X11 font Error in X11( ....

Hello! I am running analysis on the data from 4 experiments, with approximately 4600 rows (cases). My working model is: fitA1 = lme(RT~F1+F2+L,random=~1|Experiment/Subject,data=data) Model works very fine, but if I try to check whether the effect of L depends on Experiments/Subjects with: fitA2 = lme(RT~F1+F2+L,random=~1+L|Experiment/Subject,data=data) [with the idea to make: anova(fitA1,fitA2)]

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

Hello! I have posted this question at the R-HELP, general. I recently switched to Debian testing OS and explanation at the: http://cran.at.r-project.org/bin/linux/debian/ is a little bit fuzzy. Can anyone give step-by-step how-to have updated R on Debian testing and/or unstable. First, what line should be in /etc/apt/source.list? Second, how to "approach" to unstable versions? Thanks
